The invention; relates to improvements in devices for straining liquids, and farms to provide. anew and improved strainer construction Whichlis :rather simple and inexpensive, is efficient-and easy to operaie, andy `may`readily be kept in'an absolutely sanitary condition. Y

With the foregoing in View, the invention resides inthe novelsubject matterherein after described4 and claimed, thefde'scription being supplemented by the accompanying drawing. l j Fig. 1 is a vertical sectional view throughl a strainer constructed in accordance with v my invent-ion;

Fig. '2 is a horizontal sectional. view on line 2--2 of Fig. 1.

vIn the drawing above Ybriefly described, illustrating the preferred form of construe-- tion, the numeral 3 designates an ovate plate having a plurality of v fastener-receiving v openings 4 near its edge. This plateis provided Wit-ha fluid inlet 5 and vwith an outlet 6, the latter being disposed in the lobe 7 of the plate.l Both the inlet and the outlet are preferably in* the form of T-couplings,

' one branch of each couplin'ggbeingprovided screen 8 and thenl passes successively through} thisscreen and 'thefine screen" 9, before it 'dischargesthrough thev outlet 6.*
